ELECTRIC LOCOMOTIVE.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed January 23, 1915. Serial N 0. 3,979.

To all whom it may concern: I

Be it known that I, BENJAMIN S. MOORE, a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Electric Locomotives, of which the following is a specification.

My invention relates to electrically propelled locomotives and other vehicles, and it hasspecial reference to the motor mounting and center-pin construction of an electric locomotive.

One of the objects of my invention is to provide a locomotive having a simple means for centering the body on the trucks, and having the driving motors so mounted as to facilitate overhauling and reduce the num ber of parts.

In a copending application, Serial No. 837,745, filed May 11, 1914, by George M. Eaton and assigned to the \Vestinghouse Electric & Manufacturing Company, a locomotive is shown in which the pivotal center:

ing connection between the body and the truck consists of a center-pin which is carried by the body and has its lower end permanently associated with a removable crosstie between the truck side frames. The m0- tors are mounted in side-by-sidh relation between the truck side frames, and each motor comprises a semi-cylindrical lower halfframe that is rigidly secured in position and a separable cylindrical magnetizable core. In this structure, the outer sides of the removable cores are clamped to the supporting frames by separate keys, and the two inner adjacent sides are secured thereto by a single key.

According to my invention, I provide a unitary structure comprising a center-pin, a side-frame cross-tie and a key for clamping the inner sides of the motor cores in position, thus reducing the number of parts, simplifying the construction and facilitating assembling and overhauling.

My invention may best be understood by reference to the accompanying drawings, in which- Figure 1 is a view, partially in side elevation and partially in section, of a locomotive embodying my invention, the section being taken along the line I-I of Fig. 2; and Fig. 2 is a view, partially in end elevation and partially in section, of the locomotive shown in Fig. 1, the section being taken along the line II-II of Fig. 1.

Referring to the drawings, the structure shown comprises a body 1, a driving truck 2, a plurality of motors 3 mounted thereon and a unitary member 4 which serves to position certain members of the motors 3 and forms a plvota-l centering connection between the truck 2 and the body 1.

The weight of the body 1, which may be of any suitable construction, is carried on spring-loaded friction plates 5,.in any well known manner. The body is provided with a center-block 6 having a recess 7 which is adapted to receive a portion of the centering device 4, to form a pivotalcentering connection between the truck 2 and the body 1.

A plurality oftruck side frames 8, which are supported by any well known means on driving axles 9 and wheels 10, have oppositely disposed upwardly projecting portions 11 which are provided with inwardly projecting horizontal members 12 that are adapted to support the combination cross-tie and centering device 4, in a manner to be set forth.

The motors 3 are mounted in side-by-side relation above a counter-shaft 13, which is mechanically connected to the motors 3 by means of pinions 14 anda gear wheel 15, and to the wheels 10 through driving rods 16. The motors 3 severally comprise semi-cylindrical lower half-frames 17, that are rigidly secured to the side frames 8, removable cylindrical magnetizable cores 18 and a plurality of armatures 19. The opposite sides of the removable motor cores 18 are provided with shoulders 20 which are engaged by removable keys 21 that are secured to the lower half frames 17 by bolts 22 for the purpose of clamping the outer sides of the cores 18 in position. The two inner adjacent sides of the motor cores 18 are clamped in position by the combination cross-tie 4 in a manner to be hereinafter described.

The combination cross-tie 4 embodies a downwardly projecting portion 1 23 which serves as a clamping key for the inner sides of the motor cores 18 and has an upwardly projecting portion 24 which constitutes the truck center-pin and cooperates with the center-block 6 on the body to form the pivotal centering connection between the truck 2 and body '1. The combination member 4 is also provided with laterally projecting portions 25 which, in combination with the main body of the member 4:, form a sideframe cross-tie and provide means for supporting the member 4; in position upon the inwardly projecting members 12 of the side frames 3 to which said portions are secured by bolts 26.

When it is desired to overhaul themotors, the body 1 may be raised from the truck 2 without removing any bolts or pins. The truck may then be run out from under the body and the motors overhauled from above. To remove the magnetizable cores 18 from their supporting frames 17, the bolts 26 are removed, thereby permitting the removal of thecombin'ation cross-tie 4, which leaves the inner sides of the cores 18 free. The bolts 22 are then withdrawn and the keys 21 removed, which leaves both sides of the cores 18 free, so that the cores 18 may be lifted vertically from their half-frames 17.

I do not Wish to be restricted to the specific structural details shown and described, as the benefits of my invention may be secured by modified structures embodying the principles of my invention. I, therefore, desire that only such limitations shall be im-' posed as are indicated in the appended claims.

I claim as my invention:

1. In a vehicle, the combination with av body, a running gear anda pair of motors mounted thereon and severally embodying removable magnetizable cores, of a single means for positioning the cores of said motors and for providing a pivotal connection with said body.

2. In a vehicle, the combination with a body, a running gear, and a pair of motors mounted thereon and severally embodying removable magnetizable cores, of a runninggear cross-tie for locking the coresof both motors in position and for providing a pivotal connection with said body.

' 3. In a vehicle, the combination with a body, a running gear, and a pair of motors mounted thereon and severally embodying removable magentizable cores, of a single detachable member associated with said running gear and disposed between said motors for clamping the cores of said motors in position and for providing a pivotal connection with said body.

' 1. In a vehicle, the combination with a body, a running gear, a pair of motors mounted thereon and severally embodying removable magnetizable cores, and a counter-shaft mechanically connected to said motors, of a running-gear cross-tie disposed between the motors directly above the countershaft and having a downwardly projecting portion for locking the adjacent sides of the two motor cores in position and also having an upwardly projecting portion forming a centering device for the running gear.

5. In a vehicle truck, the combination with side frames, a pair of motors mounted thereon and severally embodying removable magentizable cores, of separate keys for clamping the outer sides-of the motor cores in position, and a single key for engaging the two adjacent sides of the motor cores and'having an upwardly projecting portion forming a truck center-pin.

6. In a vehicle, the combination with a body, a running gear having oppositely disposed upwardly projecting members, and a pair of motors mounted upon said running gear and severally embodying removable and magnetizable cores, of a single running gear cross-tie detachably secured to said upwardly projecting members for positioning said magnetizable cores and for providing a pivotal connection with the body.

In a vehicle, the combination with a body, a running gear and a pair of motors mounted thereon and severally embodying removable and magentizable cores, of a detachable cross-tie secured to said running gear and'having means integral therewith for clamping said magnetizable cores in position. I

In testimony whereof, I have hereunto subscribed my name this 18th day of Jan.
